ZL1 LSA Engine Break In
What really is the best way to break in these engines? Any thoughts from people who have experience in this area would be appreciated!

This is a HIGHLY debated topic. Rather that start tis topic all over again, search is your friend along with the threads mentioned above.
The short answer is, there is no clear answer. |

Short answer...I have not seen anyone make a direct correlation between break in method and any issues.
Long answer...just read those threads. |

Apex has a good thread going on this, but I will tell you almost all the ones that come in for excess oil consumption were driven easy during that critical 300-400 miles of first running. Apex has the GM tech instruction posted for replacement and crate engines. FAR different from the owners manual, but do as your comfortable. You bought the car, no one else.

How about everything/anything works for 99% of engines?
If you have a great engine 10k in, why wouldn't you think that the way you "broke it in" was the "right" way. I have "broken-in" 3 Gen 5 engines. The LFX used oil early on and gradually normalized at a quart of oil per 4000 miles. The LS3 and LSA were great from the git-go, essentially no consumption when changed at 33%. Gave ENGINE break-in no thought at all for all 3. Tried to be easy on the gears for the MT, though... |

Lots of discussion on proper break in and also the 1500 mile oil change, which isn't written anywhere. A lot of guys do it for peace of mind, which is fine, but I didn't. I followed the manual. Take it easy (no higher than 4000 rpm or 80mph) for first 1500 miles. Vary engine speed as much as possible for the first 1500 miles. First oil change at 7500 miles. I have 21000 miles on my DD and it hasn't hiccuped once. Runs perfect. I take it to the dealer for each oil change. Nothing cosmic, these aren't Ferrari's. I find it funny that folks do stuff outside what's recommended, like changing the oil at 1500 miles (to catch anything that might have gotten into the oil from a new engine.....which there is no evidence of), but again, to each his own and if it makes you feel better then do it. If you follow the recommendations, change the oil when you're supposed to then the car will run fine. If it doesn't then it's under warranty and GM will fix it.

That is why the incidence of excessive oil consumption has become so widespread with new cars and light trucks (any engine builder can attest to the seating and glaze forming) as this allows excessive blow-by and allows more oil to be drawn past the rings and be burned. The instructions we as GM techs get with replacement or crate engines instructs us to do a near full throttle run when new to 4500-5000 RPMS and then engine brake back down to load the rings properly and evenly and this seats then generally in 2-3 runs like that (I go higher) and rarely do we ever see these use oil. GM claims 1 qt every 1500-2000 mile is "acceptable" but no way. Just do a google search on a Ferrari, Lambo, or any supercar to see they seat the rings on both engine dyno and chassis dyno run to redline and engine brake down and then many also do it on a road course to check the rest of the mechanics before delivery. These mass produced cars are sent out w/out any break-in so it is all up to you the new owner. If you already have 500 miles or more on that window has passed so run it as you choose, but Apex has posted the the very instructions we get in their thread on break-in so read it and choose. Also, ask any reputable engine builder and you will get the same answer: From motorcycles to trucks...any internal combustion engine: https://www.hastingsmfg.com/ServiceT..._procedure.htm http://classracer.com/classforum/showthread.php?t=48975 http://www.drivenracingoil.com/news/...ee-horsepower/ http://www.mototuneusa.com/break_in_secrets.htm ANd a ton more.....but read the Apex thread and then ask yourself....why would GM give their techs different instructions than the average car buyer? But the bottom line is this, you paid for your car and you should follow whatever your comfortable with. Most will ignore the experts and many do just fine following the owners manual, but rarely will you ever find someone that did it the way listed and regret it. More power, longer life, and no oil use. |

break-in for the engine is not an issue. This is for the other load bearing parts such as the transmission gear and rear. My feeling is that manufacturers only list a break-in to prevent stupid situations like full throttle clutch drops off the showroom floor and similar situations. My ZL1 was at the dragstrip with 500 miles on it and was a non-oil burner. Honestly, it was one of the most durable drivetrains I have ever owned.
